Utility chooses algae monitor

United Utilities has chosen Chelsea Technologies’ ALGAE-Wader Pro and ALGAE-Station Pro systems to assist them in real time assessment of algae levels in the water sources feeding into a number of water treatment works. The systems were chosen after an extended trial period which successfully demonstrated the use of the TriLux fluorometer, from which these systems are based, in detecting chl-a, Phycocyanin and Phycoerythrin levels. The CTG ALGAE-Wader Pro is a portable system which includes the Hawk handheld display and logger. The Hawk displays all data in either numerical or graphical form, provides RAG thresholds and logs all data with both time and position stamps. The CTG ALGAE-Station Pro is a robust wall mounted system which includes the Watchkeeper display and logger. The Watchkeeper displays and logs all data, provides alarm thresholds and outputs 4-20 mA for connection to SCADA type networks.
